The student winners of the 2020 Demetriades - Tsafka - Kokkalis Prizes were announced at the end of this academic year. Manuel Bedrossian has received the prize in Biotechnology. His research is in the development of novel optical imaging devices to investigate and characterize microbial populations in extreme environments around the world. Vinayak Narasimhan has received the prize in Biotechnology. His research is in the utilization of nanostructures inspired from nature in practical biomedical applications. Tyler Ross has received the prize in Nanotechnology. His research is in guiding biomolecular filaments and motors to form structures and flow fields with patterned light. Adam Neumann has received the prize in Nanotechnology. His research involves incorporating nanoscale sensors into a mass spectrometer and using them to weigh individual molecules and perform rudimentary imaging of them. Joaquin Garcia Suarez has received the prize in Seismo-Engineering, Prediction, and Protection. His research is in fundamental research in Continuum Mechanics to better understand the behavior of civil structures during earthquakes.

Ultrasound Can Selectively Kill Cancer Cells


Professor Michael Ortiz and Professor Morteza Gharib are exploring a new technique that could offer a targeted approach to fighting cancer. Low-intensity pulses of ultrasound have been shown to selectively kill cancer cells while leaving normal cells unharmed. In the past, ultrasound waves have been used as a cancer treatment with high-intensity bursts resulting in killing cancer and normal cells. [Caltech story]

Professor Julia R. Greer Named Director of the Kavli Nanoscience Institute


Julia R. Greer, Ruben F. and Donna Mettler Professor of Materials Science, Mechanics and Medical Engineering, has been named the Fletcher Jones Foundation Director of the Kavli Nanoscience Institute (KNI). Greer replaces professors Oskar Painter and Nai-Chang Yeh, who served together as co-directors. "I am delighted to begin spearheading the wonderful enterprise of the KNI, humbly following the footsteps of my predecessors, professors Painter and Yeh. I have been a KNI member and on the board of directors since shortly after I arrived at Caltech," Greer says. [Caltech story]

A Promising Step in Returning Bipedal Mobility


Professors Aaron Ames and Joel Burdick have launched a new research initiative, RoAMS (Robotic Assisted Mobility Science), aimed at restoring natural and stable locomotion to individuals with walking deficiencies that result from spinal cord injuries and strokes. RoAMS unites robotic assistive devices—including exoskeletons and prostheses—with artificial intelligence (AI)-infused neurocontrol. "Bipedal walking is difficult to achieve in a stable fashion," says Professor Ames. "While crutches help users of the exoskeletons to stay upright, they undercut many of the health benefits that upright locomotion might otherwise provide. In addition, they do not allow users to do anything else with their hands while walking." [Caltech story]

President Rosenbaum Highlights Postdocs as "Unsung Heroes"


In a letter to the Caltech community during National Postdoc Appreciation Week, the Caltech President emphasizes the role this key group plays at the Institute. He stated, “Caltech's mission of world-leading research and education depends crucially on our postdoctoral scholars. Although their time at Caltech may be short, they quickly become vital parts of the Institute's intellectual fabric.” [President’s Letter] [EAS Postdoc Resource Page]

New Process Allows 3-D Printing of Nanoscale Metal Structures


Professor Julia Greer and graduate student Andrey Vyatskikh have created complex nanoscale metal structures using 3-D printing. The process, once scaled up, could be used in a wide variety of applications and opens the door to the creation of a new class of materials with unusual properties that are based on their internal structure.

Winners of the 2017 Demetriades - Tsafka - Kokkalis Prizes Announced


The student winners of the 2017 Demetriades - Tsafka - Kokkalis Prizes have been announced. Manuel Alejandro Monge Osorio received the prize in Biotechnology for his work with Professor Azita Emami which involves developing novel techniques for the miniaturization of implantable medical electronics in two important pillars: localization of medical devices and electrical stimulation. Pinaky Bhattacharyya was the recipient of the prize in Seismo-Engineering, Prediction, and Protection for his work with Professor Jim Beck investigating an information-theoretic approach to the problem of the optimal sensor placement for Bayesian system identification of structures using response time-history data. Bryan M. Hunter, working with Professor Harry Gray, received the prize in Environmentally Benign Renewable Energy Sources for his work on the development and characterization of a nickel-iron layered double hydroxide water oxidation catalyst with the goal of developing a solar-driven device for the synthesis of fuels, with hydrogen production as a target. The winner of the prize in Nanotechnology was Anupama Thubagere Jagadeesh whose research interests are focused on understanding the engineering principles behind designing and synthesizing programmable molecular machines.. Anupama’s graduate advisor was Professor Lulu Qian. The prize in Entrepreneurship was given to Ken Y. Chan who was advised by Professor Viviana Gradinaru. His research interests lie in developing tissue clearing technologies to render whole organs transparent for optical investigation..
